The regio- and stereo-chemistries of photo-Fries reactions of 1-naphthyl (R)-2-phenylpropanoate ((R)-1) and photo-Claisen reactions of 1-naphthyl (R)-1-phenylethyl ether ((R)-2) have been investigated in the liquid and solid phases of n-nonadecane. The results are compared with those obtained in a lower and higher viscosity liquid n-alkane. Irradiation of (R)-1 yields a prochiral singlet 1-naph...

The rice leaffolder, Cnaphalocrocis medinalis Guenée (Lepidoptera: Pyralidae), is one of the most destructive pests of rice. Electrophysiological responses of this species to 38 synthetic volatiles known to be released from rice plants (Poaceae: Oryza spp.) were studied using the electroantennogram (EAG) method. Compounds that elicited the strongest EAG responses for each physiological conditio...

Abstract Background Rosa damascena is an aromatic rose species, which cultivated for its essential oil, and widely used in perfume, cosmetic, pharmaceutical, food industries the world. This experiment was conducted to evaluate oil morphological variations of 26 Damask genotypes. For this purpose, effect harvest time, i.e., early morning or evening, sampling type, fresh dried petals, on content ...

Using 1,3-bis(chloroacetamido)propane (5) as the common intermediate, an efficient route is described to the stepwise syntheses of 1-thia-4,8-diazacyclodecane, [10]aneN2S (8), and the pentadentate macrobicycle 17-thia-1,4,8,11tetraazabicyclo[9,5,3]-nonadecane (11). During the investigation of the condensation of (5) with (8), with Li2CO3 used as a base the Li+ cation is carried over as the comp...

Rosa damascena as a holy ancient plant with modern uses in perfumery and therapeutic processes, should be more investigated due to its utilization food ingredients, preclinical clinical studies, cosmetics industry. Here, we have evaluated the proline content, total phenol of sepal petal, oil essential (EO) composition different damask rose ecotypes [(Oroumieh; OR), (Golab; GB), (Oskou; OS), (Lo...

the essential oils of the aerial parts of a. armeniaca and a. incana , collected from arasbaran area (east azarbaijan province, iran) were extracted by hydrodistillation and analyzed by gc-ms. in total, 16 and 40 constituents were identified and quantified in the oils of a. armeniaca and a. incana representing 80.5% and 84.6% of the oils, respectively. the essential oil of a. armeniaca was main...

Seaweed extract biostimulants are among the best modern sustainable biological plant growth promoters. They have been proven to eliminate diseases and abiotic stresses, leading maximizing yields. Additionally, they listed as environmentally friendly biofertilizers. The focus of present research is use a commercial seaweed biostimulant an eco-friendly product (formally named True Algae Max (TAM)...
